PT145 magazine question

I read the thread about problems with these magazines and being an old fa**, I'm confused, so need help.

1. Are newer magazines made or delivered with hanguns after June 2012 good to go or still have some problems?
2. Paraord or Promag P14 magazines work or need modification for the PT145?
3. Do Wolff magazine springs for the P14 work or modification?
4. MecGar is making P14 magazines do these work without modification?
